The cabinet underneath the sink in the bathroom has a removable floor which will give you the access you need to run an extension cord to the engine compartment. At least that access exists on my R-25SC. Two people, an extension cord and the boat hook was enough to get the job done. The Admiral found some exposed fiberglass below the cabinet, so a long sleeve and glove is recommended. I zipped tied the cord to the deck drain tube in the engine compartment so it stays out of the way when not in use and the excess cord sits in the bathroom cabinet.
